the `drill-hoes tothe frame `of the machine,

whereby the hoes .caribe changed `from double Q 'to single ranks or from single to double ranks i ,i while the machine is in motion, said mode consisting inpivoting the drag-bars of `alternate shoes to a stationary press-beam and in pivoti ing :the drag-bars of the other hoesto bearings l which depend from a `rocking cross-bar, and

in combining with the 'pivotal connections `of i y thelongitudinally-adj ustable drag-bars .hooking` or latching "devices, which will lhold said bars, wththeir hoes, either-in a forward or a backward position, `as `.will be hereinafter ex-l plained; second, providing for adjusting" the longitudinallyfmovable drill-hoes forward i or backward from the rear of the machine. by

will be hereinafter explained;` third, the employment of grain-conductors for conveying the grain from the hopper into the upper ends i of the drill-hoes,said conductors consisting of flanged troughs', which are pivoted behind to the hoes and supported by their flanges beneath the'hopper upon pins or rollers, as will be hereinafter explained;` fourth, it consists in the serrated or roughened surfaces on the plate beneath the valve or cut-off, over which surfaces the seed-slide moves, whereby the grain is prevented from escaping from the hoppers except when discharged bythe movement of the said slide, aswill be hereinafter described; fifth, it consists in making a cylindric socket in the inner side of one of the cheeks of the seed-drill tube and an oblong socket in the inner side of the other cheek of the drill-tube, in combination with a hole extending entirely through one of the cheeks and terminating in the aforesaid oblong socket, wherebythe pivot which fastens the grain-conductor to the tube can be connected to the. tube, and by the insertion of a removable pin or key will be con- `iined in place without the necessity of riveting or using screw and nut, and whereby also, the drill-tube and conductor can be very connected, as occasion may require;` sixth, in

3 vconstructing the guides for Ythe seed-slide with This invention relateslto seeding-machinesv which are designed for sowing grain in drills. v y The` `invention Sconsists, first, in` va new and improved mode of attaching the drag-bars of .portions of their upper surfaces serrated or roughened for the purpose of preventing seed The frame lof the machine consists of two f I longitudinal beams, A A, connected together and suitably braced. This frame is sustained by an axle, C, of two transporting-wheels, B 1B, on which axle is keyed a circular serpen- :tinedr zigzag cam, D. Upon end standards, 11wyghich rise from the beams A A, the hopper rds dpported, Whioh hoppei1 is provided with a hinged cover, also with a seed-slide, a,

through which rectangular oblong holes are' made for the escape of the seed.

In front of the transverse axle C and secure rigidly to the -bottom edges of the framelbeams A A is a beam, E, which extends transversely beneathsaidbeams, and has pairs of loops O O 'l Maese "secured to its lower back edge, to which one set of the drag-bars G are pivoted. Just in rear of the cross-beamE is another cross-beam, F, which is pivoted at f f to the beams A A, so

as to rock forward and backward. To this rocking beam F hangers or bearings L are'secured, so as to occupy spaces between the pairs of loops O O. To the bearings the other set of drag-bars G are pivoted at h.

To the rear ends of the drag-bars G the drillhoes G are connected by pivotsV at so that when the rocking beam F is in the position indicated'in Fig. 1 all the hoes will be in the same rank transversely; but when the beam F is released from loops p, as will be hereinafter explained, the set of hoes and drag-bars which are pivoted to the bearings L will recede and form a rank in rear of the hoes whose bars are attached to the stationary beam E, as shown in Fig. 5.

To the pivot-pin h of each longitudinallyadjustable drag-bar G a catching device, M, is pivoted, having two catches, 7L h?, on its bottom side. This catching device passes vthrough a loop, p, fastened to the fixed beam E, and will hold .its drag-bar and hoe either in a forward or a backward position. By means of a rope or chain, s, which extends backward and passes through a rocking beam, J, and which has a ring on its rear end, an attendant in rear ofthe hopper I can raise the catching device M free from its retaining loop p, and in this way detach the catch h from this loop when it is desired to form two ranks of hoes.

Rising perpendicularly from the rocking beam F is an arm, s2, to the upper end of which a rope or chain, s, is fastened, whichis carried backward and passed through the beam J. By means of this arrangement a person in rear of the machine can draw forward the longitudinallymovable hoes into the same rank with the other hoes, when'the catching device M will retain them in this position, as shown in Fig. I.

Each one of the hoes G is a tubular cast- `ing, presenting at its upper vend an oblong opening, and terminating below in a somewhat reduced circular opening. Each hoe is curved,

become engaged with any obstruction which would be liable to injure the machine. By

means of supplemental hoes through the pro-A `jection g2 of each hoe, the pins g3 g can be adjusted so as to regulate the angle of the hoe. Each hoe has a button, c', cast on its rear part at a suitable distance below its upper end,

about ,the neck of which a link, e', is com pressed, to which a chain, e-, is attached."

This chain extends up through an eye, e", and

has a ring attached to its upper end. In this way the drill-hoes are all attached to or suspended from the rocking bar J, and can be lifted free from the ground by taking hold of handle T and turning up the said bar, so that it will lie upon the upper portions of the rear standards, H,

To each hoe G a grain-conductor, G2, is pivoted at g', the pivot being confined by a removable key, This conductor consists of a lower tubular portion, g, and an open upper portion, which is flanged at n a, vand tapered. The iianges ln n are supported upon the pins or rollers d eZ of bearings (Z (Z, so that as the hoes rise and descend, the conductor will accommodate itself thereto, and at all times maintain the same position beneath the hopper. By means of the conductors the grain is conveyed directly into the upper ends of their respective drill-hoes in straight lines.

The suspension-beam J has a plate, J fastened to it in such relation -to the long and curved arm of a lever, B, that when this beam is turned up and the hoes raised free from the ground, the plate J will strike and depress said lever-arm. This lever R is adjustably pivoted to a bracket, N, which is secured to the back of the hopper I, and which is constructed with a lateral extension, N. (Shown in Fig. 7 Upon the extension N of bracket N the bifurcated rear end of a piece, a', is supported, which piece is rigidly secured to the bottom of the seed-slide a.

Between the bifurcations a2 a2 of the piece a a latch, P, engages, which latch is applied to the screw-threaded end of a pitman, j, and held fast by jam-nuts. This pitmanj is pivoted at Zl to an adjustable box, Z, which is fastened to a vibrating slotted arm, K. Arm K is pivoted to the rear end of a pin, Zc, which passes transversely through the hopper I, and to the lower end of this arm K anti-friction rollers 7c 7c are applied, which receive between them the zigzag rim of cam D. The latch P is notched and engages with the piece c, so

that the vibrating movements imparted to arm K by cam D will transmit a rectilinear reciprocating motion to the seed-slide. Zhen the beam J is thrown up and the hoes lifted from the ground thereby, the plate J will depress lever R, and thus raise the pitman-latch l?, so as to stop the motion of the seed-slide. Vhen the beam J is turned over backward and the hoes depressed again, the latch P will engage with the piece a and the seed-slide will be operated. To regulate the fiow of the seed from the hopper, the outer end of pitmanj is pivoted to a box, Z, which is secured to arm K by a bolt passed through the slot through this arm. Thus by loosening said bolt, the box Z can be adjusted up or down, and the strokes given to the seed-slide can be shortened or lengthenedw IirFigs 2, 3, and et I have represented dif ferent views of a seed distributer and regulator which is employed in the hopper I at each oblong seedrpassage through the seed-slide a,

` The novelty of this device consists in the transverse serrations c onthe uppersurfaces of the tWo lips overwhichthe seed-`slide moves. Be-

tween these two serrated lips is the passage for r the escape ofthe seed, andabove this passage` "l is a verticallyadjustable valve-plate, b', which is confined to thevertical portion b of the castingby means "of a Wedge, y c, Which `is driven fast to the bottom of the hopper With its stand ard portionrrb curving around the edge of the seed-slide `and rising perpendicularly over the same; y y 'y v Having described my invention, what I claim as new, and desire tov secure by Letters Patent, "1S- m` l l.
